The Bently Nevada AS3100S2-Z0 delivers accurate vibration measurements for machine protection. Its dynamic sensitivity stays within ±5% at 25°C. The device handles an acceleration range of 80 g peak. Amplitude nonlinearity is only 1% for clean signal output.
For frequency response, the AS3100S2-Z0 works from 1.0 to 5,000 Hz within ±10%. It also operates from 0.7 to 10,000 Hz within ±3 dB. The resonant frequency reaches 22 kHz. Transverse sensitivity is limited to ±5% of axial, which minimizes cross-axis errors.
Temperature response changes by -8% at -55°C and +10% at +120°C. Therefore, this Bently Nevada accelerometer suits both cold and hot environments.
The Bently Nevada AS3100S2-Z0 needs an 18-30 Vdc voltage source. It uses a current regulating diode from 2 to 10 mA. Broadband electrical noise measures 700 μg from 2.5 Hz to 25 kHz.
Spectral electrical noise values are low and consistent. At 10 Hz, it is 10 μg/√Hz. At 100 Hz and 1000 Hz, it drops to 5 μg/√Hz. Output impedance is 100 Ω max. Bias output voltage sits at 12 Vdc for easy system integration.
The case is isolated and internally shielded. This feature reduces ground loop interference significantly. Additionally, the design improves signal integrity in electrically noisy plants.
Temperature range spans -50°C to 120°C. Vibration limit reaches 500 g peak. Shock limit is an extreme 5,000 g peak. Electromagnetic sensitivity equals 70 μg/gauss max. Sealing is hermetic to block moisture and contaminants.
Base strain sensitivity reaches only 0.002 g/μstrain. This low value prevents false readings from surface flexing. Meanwhile, the sensing element uses PZT ceramic in shear mode for stable performance.
Weight is 145 grams. Case material is 316L stainless steel for excellent corrosion resistance. Mounting uses a 1/4-28 captive hex head screw.
The connector is side exit, 2-pin, MIL-C-5015 style. Recommended cabling is shielded twisted pair, not longer than 100 feet. Pin functions are simple: Shell is ground, Pin A is power/signal, Pin B is common.
First, clean the mounting surface thoroughly to remove dirt and grease. Next, apply a thin layer of coupling grease to improve high-frequency transfer. Then, screw the 1/4-28 captive hex head screw into the prepared hole. Tighten it to the recommended torque value.
After mechanical installation, connect the shielded twisted pair cable to the 2-pin MIL-C-5015 connector. Ensure Pin A receives 18-30 Vdc power. Pin B connects to common. The shell connects to ground for shielding.
Keep cable length under 100 feet to avoid signal degradation. For instance, a shorter cable reduces noise pickup. Finally, verify bias output voltage at 12 Vdc before starting measurements.
This AS3100S2-Z0 model provides reliable data for predictive maintenance. Its wide frequency response captures both low and high-speed machinery faults. Furthermore, the hermetic sealing allows installation in dusty or humid areas.
The 100 mV/g sensitivity is standard for most industrial vibration monitoring systems. You can directly replace older sensors without changing system gain. Additionally, the isolated case prevents ground loops when mounting on painted or coated surfaces.

1. Can the AS3100S2-Z0 measure very low frequencies below 1 Hz?
No, its frequency response drops below 0.7 Hz. For true static or near-DC measurements, this accelerometer is not suitable. Use it for dynamic vibration only.
2. What happens if I exceed the 500 g vibration limit?
The sensor may survive short-duration shocks up to 5,000 g peak. However, continuous vibration above 500 g peak can damage the internal PZT ceramic. Always stay within the specified range.
3. How do I reduce electromagnetic interference on the signal?
Use shielded twisted pair cable and keep it away from power cables. Also connect the shell pin to a clean ground. The Bently Nevada AS3100S2-Z0 has built-in shielding for moderate EMI environments.
4. Is this sensor submersible in liquids?
No, although it has hermetic sealing, it is not designed for continuous submersion. Protect the connector and cable entry from direct liquid contact. Use it in high-humidity or condensing environments safely.
5. Why does the bias output read 12 Vdc instead of 0 V?
That is normal. The AS3100S2-Z0 uses a 12 Vdc bias voltage to power the internal electronics. The dynamic AC signal sits on top of this DC bias. Your data acquisition system should remove the DC component via AC coupling.
